Puzzle toys/feeders for big cats

Hi,

I have two cats - ragdoll(f) and mainecoon(m).

I’m looking for stable and durable toys/feeder enrichments for them.

We have ball for treats and circuit (catit sense) - it’s suitable for MC. But other puzzles or feeders…he just knocks them down, because they are not very stable and generally are made for “normal” cats.

He’s big, strong cat and has 11 kg.

We are using DIY enrichments sometimes from paper rolls, cardboards and stuff, but I’m looking for something I could buy and it’s not looking like thrash on the floor :D

What feeder enrichments do you have for your big cats?

Thanks!
